Constant temperature and humidity box function we know that the equipment can simulate high temperature, low temperature, humid and hot environment. So how many tests can this device do?
1. Temperature and humidity test, which is also the main function of the constant temperature and humidity aging room, is to test the temperature and humidity of the test products.
2. High and low temperature test, the equipment can turn off the humidity function, and become a high and low temperature aging room with precise technology to test and test the test products at high and low temperatures.
3. Constant temperature test, closing humidity function, the equipment can be high temperature constant temperature test, can also do low temperature constant temperature test.
4. In addition, the constant temperature and humidity box can also carry out temperature and Humidity Cycle test, high and low temperature intersection test, etc.
5. The working principle of constant temperature and humidity box refrigeration: The refrigeration cycle uses reverse Carol cycle, which consists of two isothermal processes and two adiabatic processes. The process is as follows: refrigerant is compressed to a higher pressure by compressor adiabatic compression, the work consumed increases the exhaust temperature, and then refrigerant is heat exchanged by condenser isothermal ground and surrounding medium to transfer heat to surrounding medium. The refrigerant works by adiabatic expansion of the shutoff valve, and the temperature of the refrigerant decreases. Finally, the refrigerant isothermally absorbs heat from the object with higher temperature through the evaporator, which reduces the temperature of the object being cooled. This cycle starts again and again to achieve the goal of cooling. The refrigeration system of the aging room adopts a binary cascade Freon refrigeration system consisting of a French Taikang fully enclosed compressor. The design and application of refrigeration system can not only ensure the normal operation of refrigeration unit, but also effectively regulate the energy consumption and refrigeration capacity of refrigeration system, so that the refrigeration/dehumidification system can keep in the optimal operation state. Balanced temperature and humidity control method (BTHC) is used to control the output of heater according to the result of PID automatic calculation of the set temperature point under the condition of continuous operation of refrigeration system, and finally a dynamic balance is achieved.
What are the advantages of performance and structure characteristics of constant temperature and humidity aging room?
Constant temperature and humidity box control system:
1. Perfect modelling design: arc modelling and surface spraying treatment, high texture appearance, and the use of planar non-reaction handle, constant temperature and humidity machine easy to operate, safe and reliable.
2. Large observation window with bright and wide field of vision: Three-layer vacuum coated window and Philips energy-saving fluorescent lamp are used, no wiper is needed to defog, and clear observation effect is maintained in the constant temperature and humidity machine. The condition of the test products in the constant temperature and humidity machine can be observed at any time.
3. Separation of pipeline and control circuit of humidification system: The pipeline of humidification system in constant temperature and humidity machine is separated from power supply, controller and circuit board, which can avoid the leakage of pipeline affecting circuit of constant temperature and humidity machine and improve safety.
4. Advanced and reliable refrigeration and control system: original imported full-enclosed compressor from Europe and America, imported environmental friendly refrigerant, brand refrigeration devices, make the operation of constant temperature and humidity machine easy to learn.
Constant temperature and humidity box structure characteristics:
1. The box body is processed by NC machine tool, which is beautiful, generous, novel and has no reaction handle, and easy to operate.
2. The inner gallbladder is made of imported advanced stainless steel (SUS304) mirror panel or 304B argon arc welding. The outer gallbladder is made of stainless steel plate.
3. The temperature and humidity controllers are used to control temperature and humidity accurately and reliably.
4. Large observation window with illumination lamp keeps the box bright, and double glass is used to observe the condition of the box clearly at any time.
5. An independent temperature-limiting alarm system is set up, which automatically interrupts when the temperature exceeds the limit, so as to ensure the safe operation of the experiment without accidents.
6. The left side of the box is equipped with a 50 mm diameter test hole, which can be used for external test power or signal lines.
